  1. Past hour
  2. I just weigh my setting UW (fresh water) A7RIII + 8-15 + extension + 140mm dome = 800 g YS-D3 x2 = -50 g weefine 2300 focus light = 250 g I need Nauticam long clamps x2 , standard clamps x5 and Nauticam 125 mm double ball arm x2 I think Nauticam diameter 70 x 250 mm carbon fiber floats x2 (buoyancy = 520 g each ) are the nearest neutral buoyancy for my setup. Please let me know your thoughts and suggestions. Thanks
  3. Thanks Massimo. For me it's useful. Do you know a program to see this metadata? Maybe mediainfo?
  4. It only records at the start of the shot in the metadata not very useful Sent from my iPhone using Tapatalk
  5. Hi all, After many years I'm trying autoiso on most demanding dives with mixed results. One question: do you know where the camera stores the file ISO info? As you know you can see on the display the ISO value chosen by the camera while browsing clips on camera. Is this info stored in some metadata inside the files? Is it stored outside in some sidecar file? Is it possible to view clip ISO value once downloaded? Thank you in advance
  6. Today
  7. @adamhanlon@Phil Rudin@ChrisRoss@ajay@heynsheyns@davehicks@Akoni@hyp@oneyellowtang@Interceptor121@PeteAtkinson Thank you all for the broad, honest and facts-based discussion, opinions, etc! I finally took the plunge into the SONY A7RIV. I already went on a one-week-trip and am totally happy with it. I even had the opportunity to try out the brand-new NAUTICAM EMWL with the whole range of accessory lenses! :-) Of course, it's still a battle to accustom myself to the new functionalities etc to get the best out of it, but I quite got the hang of it.
  8. the long clamp goes in the centre between the two arms - it allows the arm to fold completely so the two arms are parallel. First though get your weight in water - you could have a different mixture of arms.
  9. Hi Everyone When I go on a photographic journey, I often make an eBook about the experience - how to get there, accommodation, etc as well as photos that I have taken and what I learnt. Several of these are about Dive adventures. These free PDF eBooks have been downloaded nearly 4000 times worldwide: https://photojourney.smiliemail.org/ or https://photojourney.smiliemail.org/?gallery for a quick image check to see. The eBooks are free and ad free. Just giving something back to the photo community.... Enjoy. Three of them - Christmas Island, Koh Lipe and Koh Libong - are concerned with snorkelling, with the latter two being almost exclusively concerned with underwater activities in Thailand. Cameras used were an Olympus TG-3 and TG-4. There are a number that deal with diving - a dive resort in Manado in Sulawesi, Preparing for a Dive Adventure, a dive resort in Dauin in the Philippines, and Underwater Stitching. Cameras used were an Olympus TG-5 and E-M1 in a Nauticam housing. Last two eBooks have just been released. The eBooks detail preparations such as transport, accommodation, clothing, photographic gear, etc as well as showing images from the photojourney. The main thrust behind the eBooks is to show what we learnt from the experience so that others will be better prepared. The links to the eBooks will redirect you to a fast Dropbox site. You do NOT have to make a Dropbox account to get access - it tries to persuade you to do this, but look for the "continue as guest" type link if asked. Grab the eBook if you like. I suggest that you get the _ebook PDF from Dropbox as it is a good compromise between file size and image quality. If you know of others who may be interested, then please pass on the above link (rather than just sending them direct to Dropbox) because this helps me keep track of the number of times the eBook is downloaded. Mention the photojourney site on any appropriate social media forums you enjoy. People are often on the lookout for new places to go, and these eBooks can help. Stay safe whilst COVID-19 causes problems. Browse the eBooks until you can browse the depths.... Enjoy!
  10. Thanks Chris for your good advice. From your recommendation , I think I will buy the long clamps x2 ( Use between housing and floats) and standard clamps x4 for the rest. But before that I have to weigh my gear UW and see how much buoyancy do I need. Thanks again.
  11. In my country, there is no dealer of Stix brand. It's so sad.
  12. Guys My partner has had a GoPro 4 for years. On a recent dive she was offered the use of a small dive light on a tray/arm. She was quite enthused! She'd like to look into getting a light but I know precious little about video lights. So I'm looking for a recommendation. The Krakens and Big Blue seem popular. I'm guessing about 2500 lumens., My partner would not be interested in anything which might qualify as "fancy". Simple, straightforward.... Any recommendations? Thanks!
  13. That's a myth about magnets, probably left over from the days of floppy disks. Modern flash memory devices are not effected by any magnet or magnetic field you are likely to encounter outside of a physics lab. Below is a snip from an article and source I found on the topic. Busting the Biggest PC Myths | PCWorld Fortunately, most modern storage devices, such as SD and CompactFlash memory cards, are immune to magnetic fields. "There's nothing magnetic in flash memory, so [a magnet] won't do anything," says Bill Frank, executive director of the CompactFlash Association. "A magnet powerful enough to disturb the electrons in flash would be powerful enough to suck the iron out of your blood cells," says Frank.
  14. Yesterday
  15. The Harbor school on Governors Island take uw donations, they teach commercial diving & are a public HS>
  16. I also use a flip, positioned between 11 et 1 o'clock. The diopter rests on top of the macro port when in use, which is typically out of the way enough to position strobes.
  17. The trick with the mega floats is to use long clamps - I have the small mega floats used together with plain non-float arms for my macro setup and find it works well. I can't use the same setup with my dome as it is too buoyant - domes tend to add some buoyancy to the system compared to macro setup - the bigger the dome, the more buoyant in general. The big mega floats have a lot of buoyancy and you generally need to use two of them for symmetry. So with either of these choices you are looking at 1.2kg of buoyancy as a minimum.
  18. Hi I use Subal for my digital photography and while not cheap it’s a great system. I suggest you buy the best camera you can to avoid changing housings too often. I use a Nikon D700 which is a professional standard camera and have had the associated Subal housing for over 12 years. Like you I also use Nikonos with film which I still think beats digital as you must think more. cheers
  19. I use a flip, positioned so the diopter goes up to about the 1:00 o’clock position. That never seem to get in the way of either a strobe or focus light. Works for me.
  20. Thanks for the replies. I was wary of the flip getting in the way also, thanks Adam for confirmation. Has anyone used the bayonet mounts?
  21. Watch out for magnetic sand. I'm also wary of strong magnets close to electronics and especially memory cards... Adam
  22. Hello, I am currently a Nikonos iii and V user and looking for a medium format housing! Looking forward to learning here and hopefully finding a nice housing!
  23. I bought a set of M67 'magnetic mounts' that I use as an alternative to the flip adapter. Very strong magnets in an AL housing. Screw one on the port, one on the lens so that you can quickly add the lens (i.e. macro) or remove it. I simply tethered the lens for my tests but a neoprene case would work as well. They came from ali-express and weren't all that cheap, but they do what I want.
  24. I don't use flip adaptors and the reason is that I find they interfere with my lighting. I am typically moving my strobes around a lot, and the flips always seem to be where I want the strobes to be! The alternative is to mount them so that they flip down...but I am also often trying to get my housing as close to the bottom as possible, and they get in the way of this. I have pockets on my dry and wetsuits, and when not in use, wet lenses etc. live in them (in neoprene bags for protection). The only exception is with long dives in very cold water. I typically use dry gloves, and can normally screw and unscrew wet lenses with these on, but if my hands get very cold due to long dives, this can get challenging. Great question!
  25. @adamhanlon and @Alex_Mustard chat about the optical accessories that can be added to the inside of a lens port to achieve different effects. Included in the discussion are extension tubes, teleconverters, adapters, diopters, and filters.
